The ''Lambdameter'' detector was specially designed for the study of c
umulative LAMBDA0-hyperons in the region of fragmentation of a target
nucleus at rest in hadron-nucleus interactions under various initial c
onditions (energy and species of primary particle, atomic number of th
e target nucleus, emission angle of a LAMBDA0-particle). The detector
is used to measure the spectra of LAMBDA0-particles in the kinetic ene
rgy range T from 40 to 150 MeV with a almost-equal-to 5 MeV resolution
, a relative systematic error of dsigma/dT within the experiment of le
ss-than-or-equal-to 5%, and an absolute systematic error of less-than-
or-equal-to 10%. It also makes it possible to determine production cro
ss sections (yields) with the same accuracy and polarization with an a
ccuracy of better than 4%. Cumulative lambdas were detected at an angl
e of 90-degrees in the lab system in the first run of the ITEP acceler
ator.
